Solution Overview

Problem

Wearable consumer electronic devices face challenges in delivering high-quality audio due to strict size limitations that affect audio volume.

Innovation Solution

The electronic eyewear device incorporates a speaker module with a carrier that emits acoustic radiation through a constrained volume using an adhesive material, which is held in a frame of the electronic eyewear device, where the speaker module is held in receptive engagement by a carrier received into the frame of the electronic eyewear device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the device size is reduced to meet wearable form factor requirements, then the device becomes more portable and wearable, but the audio volume and sound quality deteriorate

Engineering Contradiction:
Improvedevice sizeVSAvoidaudio volume
Core Design Contradiction:
Volume of moving objectVSPower

Solution Approach 1:

The patent utilizes the constrained acoustic volume created by the frame structure to redirect and focus acoustic energy. By defining a specific three-dimensional acoustic path between the speaker module and acoustic port, the system effectively uses spatial dimensionality to maximize sound output within limited device dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent optimizes acoustic parameters by carefully designing the constrained volume dimensions, acoustic port geometry, and speaker module positioning. These parameter changes enable high-quality audio delivery despite the small overall device size by tuning the acoustic characteristics of the constrained space.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the acoustic volume is increased to improve audio quality, then sound quality improves, but the device size and form factor are compromised

Engineering Contradiction:
Improveaudio qualityVSAvoiddevice form factor
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent segments the device into functional zones: the frame structure defines an external constrained acoustic volume, while the carrier module contains the speaker module and acoustic port. This segmentation allows optimization of audio quality in the acoustic volume without increasing the overall device form factor.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carrier module is received into the frame, with the speaker module held within the carrier. The frame's internal space is nested to create the constrained acoustic volume, effectively nesting functional components within each other to maximize space utilization while maintaining compact form factor.

Inventive Principle:
Principle #7Nested doll (Nesting)
